8. SAFETY ZONE CHECK
The servo delay can be calculated by the following formulas:
∆E = T
F + T
F (exponential acceleration/deceleration)
∆E = 1/2T
F + T
F (linear acceleration/deceleration)
∆E: Servo delay
: Automatic acceleration/deceleration
: Servo time constant
The sign for compensation is defined as positive when compensation is
made in the opposite direction to the move direction specified by the

1 G32 is a single–shot G code.
2 This function is ineffective if reference position return along
the X–axis is not completed.
3 The positions of the workpiece holders along the Y–axis
cannot be detected automatically.
4 When the execution of the workpiece holder detection
command is started, the specified safety zone is cleared.
5 Before the workpiece holder detection command is issued,
the workpiece holder detector must be made ready with the
M function . After the end of detection, the ready state of the
detector must be released.
